If we’re dealing with an excessively large model it may be preferable to only display the items of interest.
For this purpose we need to introduce the same filter file described in the previous tutorial but with some additions.
Here is an example of a file that reduces the items displayed for the first floor of the model Schependomlaan.
Texture=yes
Exclusive=yes
IfcBuildingStorey=01 eerste verdieping
IfcSite=yes
IfcBuilding=yes
IfcWall=yes
IfcWallStandardCase=yes
IfcSlab=yes
We now switch on the entry Exclusive to ensure that only the objects nominated in this file will be displayed.
We only want to see IfcWall, IfcWallStandardCase and IfcSlab of the first floor.
